TO ALL WHOM' IT MAY GOGERN:

Be it known thatI, S. EDWARDS, of Savannah, in the county ot Andrew, and State of Missouri, have invented anew and improved Corn-Planter; and I do hereby declare that the following is a full, clear, and exact description thereof, `which will enable those skilled in the art to` make and use the same, reference'being 4had to the accompanying drawings, forming part of this specification. I l

This invention consists in a new and improved seed-distributing apparatus, and in theigeneral construction of the machine, as hereinafter fully shown and described, whereby the feed may beidropped with certainty and cvcnly'ip clreck'- rows, and the machine readily manipulated, and all the working pa'rts put under the complete control of the driver or operator. In the accompanying sheet of drawigs- Figure 1 represents a side sectional view oi' my invention, taken in the line x x, iig. 2.

Similar letters of reference indicate corresponding parts. a 4 A, represents-thefront, and B the rear part oi the frame of the machine, said parts being connected byfa bolt, a, toadmiti of thc'front axle .being .turned for the purpose of guiding lor turning the machine. To the rear of the frontfpart, A, of the machine there is attached a circular metal plate, C, which servesvas a footboard for the driver on seat D, the latter being on the rear of the part B of the-frame, Suid part B having an arm, E, attached toit bya joint b, which allows the arm to work up and down in a vertical plane.v This arm- 'E is provided with a pendent pini, c, which, when 'the arm is adjusted downward, fits in a hole in plate C, and

4keeps the two parts, A B, rigidly connected, so that the front axle cannot turn, (see iig. 1.) Aplate, AX, is-

also attached to` the-.under side of the front part, A, ofthe frame, said plate extending hackunder the rear part,l d3, und-having a`segment-slot, o, made in it, through which a bola-p, in the rear parto'f4 the frame, passes. This bolt and segment-slot serve as a guide for the front part, A, of the frame'of the machine as the latteris turned.- The rear part, B, ofthe frame is supported by two wheels, 'F F, the peripheries of which are grooved in V`orm, to serve a`s`.cove1ers,v( see iig. 2.) The front part, A, of the frame is supported by Atwo wheels, .G Gr, which are attached rigidly to their axle H, the latter beingallowed to turn in suitable bearings.

The wheels G have their edgesor peripheries made in V form, as shown in iig. 2, -inorder to make or open the furrows which receivethe seed; ,and in order to prevent said wheels sinking too deep int-o the earth, and making the fnrrows unnecessarilyeep, concentric flanges, I, are formed on or. attached to the outer sides of the'wheels. On each end of the axle H, atthe outer sides ot' the iiang'es I, there is secured a bar, J, andthese' bars at one cnd arc bent outward, aus shown at el," to serve as .markers to point out the spots where the seed'is deposited, and onthe perpheries ofithe ianges I are secured lugs or projections e, two on each, at opposite sides of their centres. The use of these will bevpresently shown. l

, On the front part of the plate C there is secured transversely a seed-box, K, having at each end an inclined spout, L. T-hese spouts extend downward, so as to be nearly in contact with the rear parts ofthe wheels G G, as shown `in iig. 3. l In the lower part-o`f each spout L there are tted two valves',ff, the former, ji, working vertically, and the latter, f', working laterally. The valves'f are attached to one-endof levers M, the fulcrumpins g of which pass into the ends ofthe parts of the frame of the machine, and the lower ends of these levers, as the machine isdrawnalong, are acted upon by cams or wipers, 7L, on vthe axle H, the cams or wipers acting against pins z', which project from-said levers M. The cams or wipers raise the valvesf, and the latter are low-l ered by springs'j bearing upon them. The upper parts of the valvesfhave pins,7c, projecting horizontally' from them, and these pins, as the `valveefa're raised, act against inclined surfaces of levers Z, which are fitted 'en horizontal arms m, attached to the rear of the seed-box. The lower parts of these levers have each a. valve,

f', attached, and each timeithe valves f arc raised, the valves f are forced inward, so` as to prevent the discharge Y of seed from the spouts L, a space beingallcwed between the two valves to receive a dropping of seed. When the valvesf are closed under the pressure of the springs j, the valves f are opened, and the valves f c lose as the valves-j' are opened, and hence it` Vwill'bc seen that at cach dropping the quantity of seed contained between the two valves ff' is discharged. Inturning at the ends of rows., it isnecessary to stop 4the revolutions of the front wheels G G, inorder to prevent the dropping er distribution of seed, and admitof the seed in the succeeding rows being dropped inline with the hills ofthe preceding rows. This is effected by means of a horizontal bar, O, which works in guides P P on the front part A of the frame ofthe machine, :tn-arm, Q, being attached to eaehend of the bar O, and said arms having each a notch, r, made in them, to catch and'freeeive one of the lugs or projections e on the flanges I. The bar O is attached to o. lever, R, which has its fulerum-pin an upright, s, on the frontA part, A, ofthe frame of the machine. By means of this lever the bar O may be raised so that the notched arms Q will be above and free from theA lugs ory projections c of the flanges I, a notched v upright b'ar, S, being attached to the front part, A, of the frame, to hold the'lever R in an upward andl downward position. The wheels F F, which cover the seed, are kept perfectly clean or free from dirt, by means of Scrapers T, shown clearly in fig. 2. A I

I claim as new, and desire to'secur by Letters Patent- AConstructing thc frame of the machine of two parts, A B, connected by a. bolt, a, in connection with the arm E, on part B, provided with the pendent pin c,-to t in the plato C ofthe 'part A, all arranged substantially as and for the purpose set forth. l l

2. vThe seed-distributing device, consisting of the two valves ff, in the spouts L of the seed-box K, arranged. as shown, and operatedA by the levers M, and the cams or wipers 7L,from the front axle H, substantially as, shown and described. A l

3. The adjustable horizontal bar O, connected with the' lover R, and 'provided with the notched arrns Q, in combination with the lugs or projections c. on the flanges I of the wheels G G, all arranged substantially as and for the 4purpose specified. I y
